It is probably way too late for existing functions. What you might propose (but it would still be a long shot) are changes to PEP 8, which often gets used as a style guide.
You may wish to recommend that (a) *future* such functions be keyword-only, and (b) current calls be updated to act as though the underlying functions were keyword-only.
After all the bad critics here and in the bug tracker, I think I'll leave it to that.
